I have been thinking about this during the day, and looked at (what I would call) my Big Projects. Sadly, looking at them, they are not standalone often! For example, i am taking a course (with exercises) on power supply design; at the same time, I am documenting some systems, and as part of that, looking at the power supply design (but its not the main task) and taking all that experience to understand what I might want to do when designing a power supply for another project! - the common thread is "power supply design" but split over 5 separate "projects" :smiley: (and just to add some further spice, I will probably use the power supply for a controller for a beer brewing system i am working on... and beer brewing is several projects by itself!)

... hopefully this explains a little better how my work becomes a massive interconnected web; not atomic, standalone individual things
